Understanding Password Entropy
Entropy measures the unpredictability of a password. A higher entropy score (measured in bits) represents greater complexity, making it significantly harder for malicious programs or brute-force engines to guess the password.
For high security, aim for an entropy score of at least 80 bits. You can easily achieve this by increasing the overall character count of your password or introducing a mix of capital letters, numerical symbols, and non-alphanumeric special characters.
